An anal fistula (also called fistula-in-ano) is an abnormal tunnel that forms between the anal canal (inside the anus) and the skin near the anus. It’s usually the result of a previous or ongoing anal abscess that didn’t heal properly. 🔍 What Causes an Anal Fistula? Chronic anal abscesses (most common) Blocked anal glands Inflammatory bowel disease (especially Crohn’s disease) Tuberculosis or HIV (in rare cases) Trauma, radiation, or surgery ✅ Symptoms Persistent or recurrent pus or discharge near the anus Pain, especially when sitting, walking, or during bowel movements Swelling or a lump near the anus Bleeding Irritation or redness around the opening Fever or chills (if infection is present) ⚠️ If an abscess reappears or continues to drain, a fistula is likely present. 📌 Types of Fistulas (Parks Classification) Type Description Intersphincteric Between internal and external sphincters (most common) Transsphincteric Passes through both sphincters Suprasphincteric Extends above external sphincter Extrasphincteric Outside the sphincter muscles (rare and complex) 🧪 Diagnosis Physical exam (look for external opening near anus) Digital rectal exam Probing of the tract (by a doctor) MRI or endoanal ultrasound (for complex fistulas) Fistulogram (X-ray with dye – rarely used now) 💊 Treatment ❗ Fistulas do not heal on their own — surgical treatment is usually required. 🔧 Surgical Options Procedure Description Used for Fistulotomy Open the fistula tract to allow healing Simple, low fistulas Seton placement Thread placed in tract to drain and slowly cut through muscle Complex or high-risk fistulas LIFT procedure Ligation of the fistula tract at its origin Deep, transsphincteric fistulas Fibrin glue / plug Minimally invasive, fills the fistula tract Low success rate, used selectively Advancement flap Covers internal opening with a flap of rectal tissue Complex or recurrent cases VAAFT / laser ablation Minimally invasive options For selected patients

PILES (HEMORRHOIDS) Piles (medical term: hemorrhoids) are swollen veins in the anus or lower rectum, similar to varicose veins. They can be internal or external, and are a very common cause of anal pain, itching, bleeding, or lumps. 🔍 Types of Hemorrhoids Type Location Symptoms Internal Inside rectum Usually painless, may bleed during bowel movements, can prolapse (bulge out) External Under the skin around anus Painful, itchy, may form hard lumps (thrombosed) Thrombosed Blood clot in external hemorrhoid Sudden, severe pain; swelling; purple or blue lump ✅ Common Symptoms Bright red blood on toilet paper or in stool Itching or irritation around the anus Pain or discomfort, especially while sitting Lump or swelling near the anus Feeling of incomplete emptying Mucus discharge (in prolapsed piles) 📌 Causes and Risk Factors Straining during bowel movements Chronic constipation or diarrhea Prolonged sitting (especially on the toilet) Low-fiber diet Obesity Pregnancy Aging (loss of tissue support) 💊 Treatment Options 🔹 Home and Lifestyle Treatment (for mild to moderate piles) High-fiber diet (whole grains, fruits, veggies) Fiber supplements (psyllium, methylcellulose) Plenty of fluids (8+ glasses/day) Avoid straining Don’t delay bowel movements Sitz baths (warm water soak for 10–15 minutes) Cold packs for swelling Topical creams: Hydrocortisone (for inflammation) Lidocaine (for pain) Witch hazel pads 🔹 Medications Oral pain relievers (e.g., ibuprofen or acetaminophen) Flavonoid-based medicines (e.g., Daflon) in some countries 🛠️ Minimally Invasive Procedures (for persistent or severe hemorrhoids) Procedure Description Notes Rubber band ligation Cuts off blood supply; piles shrink and fall off Most common office treatment Sclerotherapy Injection causes vein to collapse For small internal hemorrhoids Infrared coagulation Laser or light burns hemorrhoid Painless, quick recovery Cryotherapy Freezing the hemorrhoid Less commonly used

ANAL FISSURE An anal fissure is a small tear or cut in the lining of the anus that can cause pain, bleeding, and spasms during or after bowel movements. It’s a common condition and usually not serious, but it can be very painful. 🔍 Causes Passing hard or large stools Chronic constipation or diarrhea Straining during bowel movements Childbirth Anal trauma (e.g., during anal sex) In rare cases: Crohn’s disease, HIV, tuberculosis, or cancer ✅ Symptoms Sharp, burning, or stabbing pain during or after bowel movements Bright red blood on toilet paper or in stool Visible tear near the anus Itching or irritation Spasm of the anal sphincter (can worsen the tear) 📌 Types of Anal Fissures Type Description Acute Recent tear, looks fresh, usually heals in a few weeks Chronic Lasts >6 weeks, edges may become thickened or scarred, may require surgery 💊 Treatment 🔹 Conservative/Home Treatments (First-Line) High-fiber diet (25–35g/day) to soften stool Stool softeners (e.g., docusate) Warm sitz baths (10–20 minutes, 2–3 times daily) Drink plenty of water Avoid straining or sitting too long on the toilet 🔹 Medications Topical anesthetics (e.g., lidocaine) for pain Topical nitroglycerin or calcium channel blockers (e.g., nifedipine, diltiazem) to relax the sphincter and increase blood flow for healing Botox injection into the anal sphincter (relaxes muscle to help healing; lasts a few months) 🔧 Surgical Options (for chronic or non-healing fissures) Procedure Description Lateral internal sphincterotomy (LIS) Gold standard; small cut in sphincter to reduce spasm and promote healing Fissurectomy Removal of scarred tissue Advancement flap Used for fissures not healing due to poor blood supply Surgery has high success rate (>90%) but slight risk of incontinence (gas or stool) 🧼 Prevention Tips Maintain regular bowel habits Use fiber supplements if needed (e.g., psyllium) Avoid straining Keep the anal area clean and dry Treat any underlying constipation or diarrhea 🚨 When to See a Doctor Pain lasts more than 6 weeks Recurrent bleeding No improvement with home treatment Suspected chronic fissure or other anal conditions (e.g., hemorrhoids, abscess, cancer)
